Conklin Nozac 1937
My father's old Conklin Nozac, which was used to write thousands of prescriptions (he was a GP), is in good working order after I repaired the filling system with an "O" ring. The only problem left is a missing clip in the cap (attached pics). Any suggestions as to what can be done? New cap? Can a new clip be fitted?
I would be grateful for any help.
